Validator
Definition
A validator is a network participant that verifies transactions, proposes blocks, and maintains consensus in Proof of Stake blockchains. Validators stake tokens as collateral and earn rewards for honest participation. Quantum-resistant validators use post-quantum signatures for all consensus operations.
Technical Explanation
Validators run full nodes processing all transactions. They sign block proposals with their private keys, attest to chain heads, and participate in finality protocols. The validator set collectively maintains network security through cryptographic proofs and economic incentives.
Post-quantum validator requirements: generating Kyber-768/SPHINCS+ key pairs, signing operations with SPHINCS+, handling larger signature sizes in attestations, and maintaining uptime. Hardware requirements may increase slightly for signature computation and storage.
SynX Relevance
SynX validators use SPHINCS+ signatures for all consensus participation. Validator credentials are quantum-resistant from registration through all operations. Running a SynX validator secures a quantum-resistant network while earning staking rewards.
Frequently Asked Questions
- How much do I need to become a validator?
- Minimum stake requirements vary—check current SynX parameters. Delegation allows participation with smaller amounts.
- What hardware do validators need?
- Standard server specifications plus additional capacity for post-quantum signature operations.
- Can validators be slashed?
- Yes—double-signing or extended downtime can result in stake slashing as a security mechanism.
